CFI CFI Deception Detection & Credibility Assessment 2 — Questions and Answers
Question 1: Which verbal indicator is often associated with deception during a forensic interview?
- Using past tense consistently throughout a narrative
- Excessive use of qualifiers like 'I think' or 'I believe' when describing personal experiences (Correct answer)
- Providing spontaneous corrections to earlier statements
- Including rich sensory details in the account
Correct answer: Excessive use of qualifiers like 'I think' or 'I believe' when describing personal experiences
Excessive qualifiers reduce commitment to statements and can indicate uncertainty or an attempt to avoid direct lies.
Question 2: The Cognitive Interview technique enhances memory retrieval by:
- Using leading questions to guide recall in a specific direction
- Reinstating the context of the event and encouraging multiple recall attempts (Correct answer)
- Administering polygraph tests before the interview
- Showing photographic evidence to prompt recognition
Correct answer: Reinstating the context of the event and encouraging multiple recall attempts
The Cognitive Interview uses mental reinstatement and multiple retrieval strategies to maximize accurate and complete recall.
Question 3: When assessing credibility, a CFI should understand that stress during an interview:
- Always indicates deception in the subject
- Can be caused by both truthful and deceptive subjects and must be interpreted carefully (Correct answer)
- Is only experienced by innocent subjects who are nervous
- Has no meaningful impact on behavioral indicators
Correct answer: Can be caused by both truthful and deceptive subjects and must be interpreted carefully
Stress responses can occur in both truthful and deceptive individuals, requiring careful comparison against established baseline behavior.
Question 4: Reality Monitoring (RM) in credibility assessment focuses on:
- Polygraph results compared across multiple sessions
- Differences in memory characteristics between perceived and imagined events (Correct answer)
- Digital surveillance data and metadata analysis
- Witness identification procedures and lineups
Correct answer: Differences in memory characteristics between perceived and imagined events
Reality Monitoring assesses whether statements contain characteristics typical of actual memories versus fabricated or imagined accounts.
Question 5: Which of the following is NOT a criterion in Criteria-Based Content Analysis (CBCA)?
- Logical structure
- Quantity of details
- Polygraph score (Correct answer)
- Spontaneous corrections
Correct answer: Polygraph score
CBCA analyzes statement content criteria and does not include physiological measurements such as polygraph scores.
Question 6: When a subject provides an alibi during a forensic interview, a CFI should:
- Accept it without further verification if it sounds plausible
- Immediately confront the subject with any contradictory evidence
- Document the alibi and seek corroboration through independent investigation (Correct answer)
- Disregard it as inherently self-serving
Correct answer: Document the alibi and seek corroboration through independent investigation
Alibis should be documented and independently verified to determine their validity through corroborating sources.
